ALARM-LOCK.

Speccation of Letters Patent No. 27,856, dated April 10, 1860.

To all 'whom it may concern:

Be it known that I, JOSEPH ZIEGLER, of Baltimore, in the State of Maryland, have invented a new and useful Alarm-Lock for Use in Stores, Sac.; and I do hereby declare the following to be a correct description of the same, reference being had to the accompanying drawings, in which- Figure l is a perspective view of a portion of a store counter with my improved alarm lock applied to the cash drawer. Fig. 2, is a vertical section from front to rear through the apparatus; and Fig. 3, is a plan or top view of the trigger and its connections.

The nature of my invention consists in controlling the opening of the cash drawer of a'shop or store by means of a treadle attached to the Hoor, and in combining at will with the treadle a bell trigger in such a manner that the drawer can not be opened without an alarm being sounded.

The object of the invention is to prevent the cash drawer from being robbed by a person standing on the outside of the counter, and to prevent the drawer being opened even by a person standing inside the counter without sounding an alarm bell.

In the drawings the same letter marks the same part in all the figures.

A marks the counter; B, the drawer; O the floor; D a hollow standard through which the bolt works; E the case inclosing the treadle and trigger; F the treadle; Gr, the trigger; H, bent lever; I piece which supports the bent lever H and in which it turns; J sliding rod worked by bent lever H.

a marks the slots through which coin is introduced into the drawer; Z9, keyhole for common lock; c recess in the bottom of the drawer; d, spring bolt received into recess c to lock the drawer; e hinge between bolt CZ and treadle F; f hinge of treadle F; g fulcrum of trigger G; eyelet in end of trigger; z' wire attached to eyelet it and to a bell of any suitable kind, and in any desired position, for giving the alarm.

The drawer B may have an ordinary lock in the usual position not controlled by the treadle. It will usually, however, be locked only by the bolt l which is forced up into the recess c by a spring in any well known way. This bolt works inside the hollow shaft D, and is hinged at its lower end to the treadle F so that when the treadle is depressed by the foot the bolt is drawn out of the recess, and the drawer can be opened.

When the drawer is again closed the bolt is again thrown by its spring into the recess and locks the drawer.

When it is desired that the drawer shall be opened by the use of the treadle without giv- -ing an alarm, the bent lever I-I is turned to such a position as to throw the rod J under the trigger G so as to hold up the inner arm of the trigger and depress the outer end or arm. When in this position (as seen in Fig. 2,) the treadle willy not touch the trigger when it has descended far enough to release the bolt Z from the recess c, and consequently no alarm will be given when the drawer is opened. But when it is desired to give an alarm the bent lever H, which can readily be operated by the foot, is turned to a position to retract the rod J from under the trigger G, when its inner arm, drawn by the bell wire, will descend and its outer. arm rise to such a position that when the treadle F is pushed down its under surface will come in contact with the trigger and ring the bell to which its inner end 71, is connected.

The case E covers the treadle, trigger and bell wire and protects them from being tampered with. The bell wire may be conducted, as in Fig. 2, underneath the floor, and be attached to a bell in any convenient position.

The advantage of the arrangement is 0bvious. The treadle is entirely out of the reach of a person standing on the outside of the counter, and when the bent lever is properly set, the opening of the drawer by means of the treadle can not be eected without its being immediately announced by the bell. At other times than during the hours of business, the drawer will be protected by a lock of any usual or desired form.

Having thus fully described my invention, I do not claim connecting a drawer with an alarm bell that will sound when the drawer is opened; but

What I claim isl. Controlling the opening of a drawer by means of a treadle operated by the foot substantially in the manner described.

2. I also claim connecting or disconnecting at will the treadle which controls the drawer with an alarm bell substantially in the manner and for the purpose set forth.

The above specification signed and witnessed this 5th day of March A. D. 1860.
